How to manage oranges in the latest winter

Citrus is a very popular fruit, unlike other fruit trees, citrus is an evergreen fruit tree with no obvious dormancy period, and the picking period is also concentrated in autumn and winter, so seasonal culture is a very important part of annual management. it is directly related to the tree potential and yield of the following year. So how to manage oranges in winter? Let's take a look.

1. Timely harvest

Some oranges are picked in winter, but some growers don't pick them until spring comes. However, when the fruit is too much on the tree, it will also consume the nutrients of the tree, which is not conducive to the recovery of the tree, so that the branches are easily frozen and the extracted branches are relatively weak, and picking too late is not a good thing, which will reduce the quality of the fruit.

2. National Qingyuan

After picking, the work of clearing the garden in winter is more important, because the sources of diseases and insect pests that harm citrus are hidden in litter, weeds and fruits. Therefore, it is necessary to carry out a comprehensive garden cleaning, centralized treatment of disease and insect branches, dry and withered branches, fallen leaves, fallen fruits and weeds, which can be burned or buried deeply. In this way, the base number of diseases and insect pests can be greatly reduced and the occurrence degree of diseases and insect pests in the coming year can be reduced.

3. Protect the green leaves through the winter

Citrus is an annual evergreen fruit tree, when the temperature is low in winter, it will enter the dormant period, when the nutrients of the tree are mainly concentrated in the green leaves. Therefore, to protect green leaves through the winter is actually to protect citrus trees from loss of nutrients during the overwintering. The protection of green leaves can start from fertilization, cold protection, soil cultivation, etc., in order to protect the green and safe through the winter.

4. Pruning before budding

Some pruning is needed only before sprouting in spring after picking, and the freezing injury areas can be carried out in the middle of February, and the young trees should be trimmed lightly when pruning, the main purpose is to cultivate 3-4 main branches with uniform distribution, and the secondary main branches should be arranged reasonably on the main branches. The purpose of the fruiting tree is to create a ventilated and transparent tree with three-dimensional fruit, which can be pruned by the pruning technique of "one opening, two thinning and three retraction".

5. Do a good job of fertilizing

Citrus consumes a lot of nutrients after fruiting, so it is necessary to apply fertilizer in time after picking to promote the accumulation of nutrients and lay the foundation for flower bud differentiation and flowering and fruiting in the coming year. Fertilization after fruit harvest should also be overwintering fertilizer, base fertilizer, returning sun fertilizer, moon fertilizer and so on, the best application time is in late autumn and early winter, and then the plant enters the dormant period, the root system will no longer be rapidly nourished, and the effect of fertilization is not good. Fertilizer is mainly organic fertilizer, combined with the application of biological fertilizer.
